Hi,
To answer your first question, if you click on "More", it should take
you to the relevant entry in the Help Browser. If it doesn't, there is
something wrong with your installation.
In your example, the reason that the Show[] command didn't work is that
your previous commands didn't evaluate properly (you can tell this
because the output of the Show[] command contains the unevaluated
earlier commands, rather than the Graphics objects you would get if
they had evaluated correctly.
I can't test your example because it doesn't include the definition of f.
